Three pups 2 are April pups and one is late may. The 2 April pups poop is clearing up a little but the may is only pooping dark tarry looking blood. Been worming them with ne*ex since i got them and someone told me to try pyran**ll 3 days in a row today will be the 3rd day. Plan on taking them to vet this afternoon just wondering if anyone has seen this before.

had same problem with 2 same age vet gave them valbazen

Sounds like hookworms,try panacur three days in a row,1 CC per 10 pounds.

Vet said whipworms they're on panicur and antibiotics
